BACKGROUND Technical Field

The present disclosure relates to a nozzle structure of watering device;to be more concrete, which is a rotor nozzle structure with theadvantages of easy assembly and steady operation.

Related Art

The conventional structure of rotor nozzle as claimed in patent U.S.Pat. No. 9,931,652 disclosed a housing 2 having a conical chamber 3 asan accommodation for a rotor 12 in column shape, the rotor 12 having oneend deployed with water outlet hole 14 connecting to the outlet opening6 of a spray gun, and the intermediate element 25 having a sphericalsurface against inner wall of the conical chamber 3 for the rotor 12 inan eccentric arrangement to the longitudinal axis of the conical chamber3. In this way, when the fluid flows into the chamber 3, it rotates therotor 12 with tilt current then turning into a swirling steam of 360degrees running out of the outlet opening 6. Besides, the rotor 12 ofthis kind of rotor nozzle would also rotate in the chamber 3, thusoutput fluids would disperse.

SUMMARY

The present disclosure aims to provide a rotor nozzle adopting alongitudinal chamber to apply on a handy spray gun and preventing therotor from rotating, so as to let output fluids concentrate.

Based on above-mentioned goals, the present disclosure provides astructure of rotor nozzle installed inside the spray unit of a wateringdevice, the spray unit is composed of a mounting member and a housingfor mutually defining a chamber having one water inlet and one wateroutlet, and the chamber deployed with a rotor for its end of wateroutlet connecting to the water outlet side. Wherein, at least onestopper set on the inner side of the chamber near the water outlet sideis correspondingly matched to multiple guide members on the end of wateroutlet of the rotor.

Thanks to the deployment of a stopper, it secures the rotor in a tiltarrangement and dismisses the conventional conical chamber to be appliedto existing spray nozzles. Furthermore, the rotor has a spherical oneend connecting to the water outlet of the watering device. Therefore,the water outlet side of the rotor forms at least two annularpositioning areas. The present disclosure further provides a wateringdevice for accommodating aforementioned structure of rotor nozzle.

DETAILED DESCRIPTION

Hereinafter to deliberate more specifically the embodiment of thepresent disclosure, the narration sets forth from which the water outletof the adjustable watering device for a better understanding by thetechnicians skillful in the arts.

FIG. 1 to FIG. 4 illustrate a spray unit 100 of a watering device, thespray unit 100 is rotatably installed on the base 200 of the wateringdevice and mainly assembled by an adjusting member 10 and a mountingmember 11 correspondingly. Multiple spray heads are set between theadjusting member 10 and the mounting member 11, the spray headsrespectively have a water outlet and a water inlet between the adjustingmember 10 and the mounting member 11, the mounting member 11 isconnected to the water inlet side 101 of the base 200 of the wateringdevice, and the water inlet side 101 is connected to a water supply.Thus, due to the relative rotation between the spray unit 100 and thebase 200 of the watering device, one of the spray heads can be connectedto the water inlet side 101 of the base 200, so that water from thewater supply flows through the water inlet side 101 and inside of therotor nozzle, and ejects out from the water outlet side 102.

One of the spray heads has structure of rotor nozzle, the structure ofrotor nozzle consists of a housing 15, a rotor 20, a flow director 40.Wherein, the housing 15 is roughly a tubular in shape having its frontend engaged to the inner wall of the adjusting member 10, so that thewater outlet side 102 of the housing 15 located on the adjusting member10, and the housing 15 has its rear end connected to the mounting member11 for mutually defining a chamber 17 with a longitudinal interior.

The flow director 40 has an annular base 41 located on the rear openingof the housing 15 and the block 12 on the side wall of the mountingmember 11, so that the flow director 40 and the bottom of the mountingmember 11 are arranged in a partition formation. Besides, the flowdirector 40 has a center base 45 spaced from the annular base 41, aposition rod 47 protruding from the center base 45 forwards to thedirection of the water outlet 102, and multiple guide vanes 43connecting to the inner side wall of the annular base 41 and the outerside wall of the center base 45, the guide vanes 43 are extending alongthe radial direction of the center base 45 and tangent to the centerbase 45 respectively at a predetermined angle, a swirl opening 46 isdefined between the adjacent guide vanes 43. In other words, the swirlopening 46 is arc-shaped and penetrates the two opposite sides of theannular flow director 40.

The rotor 20 is installed inside the chamber 17 and forms a hollowcolumn having two ends as a water inlet 21 and a water outlet 22.Wherein, the rotor 20 has an inner wall fixed with multiple currentblades 26 extending to the water inlet 21 in a crossover formation. Therotor 20 has a spherical end 27 disposed of a water outlet 22 connectingto the water outlet side 102 of the adjusting member 10, and thespherical end 27 and the water outlet side 102 form a complementarymechanism. Besides, the rotor 20 has its water inlet 21 confined betweenthe inner wall of the chamber 17 and the annular track of the positionrod 47 of the flow director 40 for the rotor 20 in an eccentricarrangement, leaning backward and outward, to the water outlet.

The present disclosure provides an embodiment, wherein the chamber 17near the water outlet side 102 is a longitudinal interior with multiplestoppers 18 protruding on the inner wall in annular form, and a slot 19is formed between the stoppers 18, multiple stop rods are protrudedradially on the spherical end 27 of the rotor 20 as guide members 28 andlocated on the slot 19. Besides, each stopper 18 has a bevel on itssurface for guiding the surface of the rotor 20 in tilt arrangement, thewater outlet side (the spherical end 27, guide members 28) of the rotor20 forms at least two annular position areas, the rotor 20 rotatessteadily and prevents the rotor 20 from rotating, in order to generate acentralized linear current spraying out from the water outlet 22 of therotor 20 instead of the conical spurt produced by rotation of theconventional rotor.

It is worth mentioning that the position rod 47 of the flow director 40is in a line with the water inlet side 101 and the water outlet side102. A rod body 25 is extending from one end of the water inlet 21 ofthe rotor 20 along the rear end of the current blade 26 for locating onthe outer wall of the position rod 47 to thereby steady the rotationtrack of the rotor 20. When water of the water supply flows to the swirlopening 46 of the flow director 40 from the water inlet side 101, tiltcurrent generated in the chamber 17 drives the rotor 20 to rotate,fluids flows through the water inlet 21 of the rotor 20 to the wateroutlet side 102 of the spray unit 100 and swirling steam outputs by therotation of the rotor 20.

Please refer to FIG. 5, it illustrates a spray unit of another wateringdevice. In this embodiment, a bevel is set on the chamber near the waterinlet side 101 for guiding the surface in rear of the rotor 20. Thechamber near the water outlet side 102 has a longitudinal interior, andthree stoppers 18 protruding on its inner wall are arranged equiangular.Multiple slots are arranged radially in an annular form on the wateroutlet of the rotor 20, the slots are provided as guide members forplacing the stoppers 18, in this way, the rotor 20 rotates steadily withits tilt arrangement and prevents the rotor 20 from self rotating.

The present disclosure provides an embodiment, wherein the number of theguide members 28 is integer multiple of the number of the stoppers 18,to maintain rotational balance. However, the number of the stoppers 18also can be only one, to locate the rotor 20.
